In addition, the Operation brings with it a whole host of goodies, including the New Falchion Case and Knife, new in-game skin collections, the return of missions and a new feature which is Profile Ranks.

Casual-mode rulesets have been tweaked as well as a few UI fixes. There have been a number of Miscellaneous changes which appear intended to fix a variety of issues, as well as a game engine update.

And finally, de_cache, de_season and de_mirage have been patched to optimise the maps even further.

The full patch notes can be found below:
